The brake pipe of the newest AC Metro rake burst at MG Road station during the morning rush hour on Monday, disrupting services for nearly 40 minutes.
“When the driver applied the brakes after entering the station, the brake pipe burst, bringing the train to a halt,” said a Metro official.
The snag occurred at 10.44am. Normal services resumed at 11.23am.
Seven Dum Dum-bound and as many New Garia-bound trains had to be cancelled. Trains were operated between New Garia and Maidan during the period.
Snags have dogged the AC rakes since their introduction. Metro officials admit that the glitch-prone trains spend more time in the maintenance shed than on the tracks.
The rake that developed a snag on Monday had arrived only last month from the Integrated Coach Factory in Perambur. “It had developed snags even during earlier commercial runs,” said an official. “Monday’s was the most unusual snag. We have sent the rake for a thorough inspection and repairs.”
